Frequency Translator / Jitter Attenuator

10MHz reference

GENERAL DESCRIPTION

The ABFT series is an Ultra Low Jitter VCXO based frequency translator; ideally suited to improve Jitter characteristics of the input signal. This device is

designed to provide input clock smoothing - while providing Phase and Frequency Locked higher frequency translated output.

Typical application will take a 10MHz reference frequency and phase & frequency lock it to either a 20MHz or a 40MHz Low Jitter VCXO. The implemented

technology significantly attenuates the jitter content of the 10MHz reference signal; while keeping the higher frequency RF Output - Frequency and Phase

Coherent with the input 10MHz reference signal.
